I don't usually point to sales, but Insty says that Kaspersky antivirus is on sale for $19.95. That's quite a good deal, and I've always thought that Kaspersky was one of the better products. They release new signatures quicker than the other major vendors (Symantec, McAfee), and I haven't heard complaints that they're a resource hog like the others.
If you're looking for a new antivirus anytime soon, this seems an unbeatable price.
And note to FTC: drop dead.
